To all whom it may concern:

Be it known that I, GUILLAUME WEBER, citizen of the Republic of France,residing at Hayange, Lorraine, France, have invented new and usefulImprovements in Explosives, for which I have filed an application inermany July 9, 1915, in England Aug. 30, 1915, and in Switzerland Aug.3, 1915, Patout No. 72,057,) of which the fOllOWlHg'IS a specification.

This invention relates to a high power explosive formed by a mixture ofcombustible organic substances or carbon with combustible metallicpowders such as aluminium, antimony, magnesium, silicium, etc., saidmixture being shortly before use, impregnated with liquid air, whichlatter is added to the mixture only after the mass has been introducedeither into the bore hole or into a special cartridge. The impregnationof the cartridge can also be effected in a vessel filled with liquid airin which it may be left until complete saturation.

By mixing the combustible organic substance or substances which arecapable of absorbing liquid air, with the combustible metallic powder orpowders, the proportion of combustible metallic powder may be reduced toless than 150 grams per liter of composition.

It will be noted that the absorbent for liquid air is formed by acombustible substance and not by an inert one.

The liquid air rich in oxygen may be remetallic powder in the proportionof less.

than 150 grams of combustible metallic powder per liter of composition,said mixture being impregnated with liquid air.

2. An explosive composed of a mixture of combustible organic substancescapable of absorbing liquid air with combustible me tallic powders, inthe proportion of less than 150 grams of combustible metallic powdersperliter of composition, said mixture being impregnated with liquid air.
